The patch titled
Subject: treewide: use PHYS_ADDR_MAX to avoid type casting ULLONG_MAX
has been removed from the -mm tree. Its filename was
treewide-use-phys_addr_max-to-avoid-type-casting-ullong_max.patch
This patch was dropped because it was merged into mainline or a subsystem tree

From: Stefan Agner <stefan@xxxxxxxx>
Subject: treewide: use PHYS_ADDR_MAX to avoid type casting ULLONG_MAX
With PHYS_ADDR_MAX there is now a type safe variant for all bits set.
Make use of it.
Patch created using a semantic patch as follows:
// <smpl>
@@
typedef phys_addr_t;

-(phys_addr_t)ULLONG_MAX
+PHYS_ADDR_MAX
